# What is the maximum number of electrons that can be found in any orbital of an atom?

Dec 29, 2017

To calcualate the maximum number of electrons use this formula:
$2 {n}^{2}$
The letter $n$ represents the number of electronic shells form 1 to 7.

#### Explanation:

E.g. If you want to calculate the maximum number of electrons in the third shell instead of $n$ you put in your calculator $3$.

$2 \cdot {3}^{2} = 18$

In the third shell are 18 elelctrons max.
